Abstract

The present invention discloses a quality control method of Chinese medicine composition for curing infantile common cold. Said method adopts thin-layer chromatography to identify active effective components of scutellaria root, arctium seed, gardenia fruit and forsythia fruit, and utilizes high-performance liquid determination method to determine the content of baicalin.

Description

technical field [0001] The invention relates to a quality control method of a traditional Chinese medicine composition preparation, in particular to a quality control method of a traditional Chinese medicine composition preparation for treating infantile colds. Background technique [0002] Because children's viscera are delicate, their spleen and stomach are weak, and they are susceptible to wind pathogens, children's cold is one of the most common exogenous diseases in infants and young children. It can occur all year round, especially in winter, spring, and autumn. After the onset, it is easy to affect the digestion and absorption functions of the spleen and stomach, and stop eating and stopping milk. The clinical manifestations of this disease are fever and chills, cough, runny nose, sneezing, etc. as the main symptoms. Xiaoer Ganmaoning Granules have a good effect on the treatment of this disease. Honeysuckle and forsythia are mainly used to disperse wind-heat from the ...
